Has anyone tried the Oral-B Dual Action power brushes? They are so expensive that I hate to get them if they don't work as well as the regular power ones.
Is that the one with the rechargable battery? if so, my problem was that the battery wore out and couldn't be fixed. The replacement brushes were expensive too. I don't think they did any better than the replaceable battery ones like Braum or Crest (or was it Colgates?)
Any of them must be used correctly and regularly. They aren't a substitute for regular visits to the dentist. Some people form tartar on their teeth quite fast. Even regular brushing doesn't seem to keep it all off.
I had an Oral B 3-D and thought it was great, but had the same problem with the re-charger. Then I picked up a $6 battery brush in K-Mart (2win Spin by Orawave) and I swear it's just as good. I even e-mailed to tell them so and will buy them by mail if K-Mart is out. Agnes is right, though, none of the brushes are going to do much by themselves.
